My Second Senior Brother Is a Mortal But Strong

Chengzi said, "They ascend during the day, but I can't sleep at night."

The junior girl asked, "Why can't you sleep if others ascend?"

The prefect interjected, "Because he helps other people to ascend to immortality, while he himself is still mortal."

A moment later, Chengzi helped the prefect pass his final trial, and sent him on his way to immortality.
